TLDR
The designs of some tree LANs that use collision avoidance switches, including broadcast star and CAMB tree (Collision Avoidance Multiple Broadcast tree), and a possible implementation of a collision avoidance switch using currently available photonic devices are described.Abstract:
Packet collisions and their resolution create a performance bottleneck in random access LANs. A hardware solution to this problem is to use collision avoidance switches. These switches allow the implementation of random access protocols without the penalty of collisions among packets. We describe the designs of some tree LANs that use collision avoidance switches. The collision avoidance LANs we describe are broadcast star and CAMB tree (Collision Avoidance Multiple Broadcast tree). We next present a possible implementation of a collision avoidance switch using currently available photonic devices. Finally, we show the performance of broadcast star and CAMB tree networks using simulations.read more

TL;DR: Presents a design of a collision avoidance switch for the collision avoidance multiple broadcast (CAMB) tree using transistor-transistor logic (TTL) devices and results show that the slotted broadcast star achieves better performance than the unslotted Broadcast star, especially when the traffic load is heavy.
Performance analysis of a broadcast star local area network with collision avoidance. Part 1, Infinite station population model
Kunio Goto,Tatsuya Suda +1 more
TL;DR: It is shown through simulations that a broadcast star operating under synchronous mode yields better performance than when operating under asynchronous mode, where transmissions of packets are not confined to the beginning of slots and stations start transmission at any time.

Performance analysis of a broadcast star local area network with collision avoidance
TL;DR: In this article, the performance of a broadcast star network under the assumption of synchronous operation of a network is analyzed, and it is shown through simulations that broadcast star operating under synchronous mode yields better performance than when operating under asynchronous mode, where transmissions of packets are not confined to the beginning of slots and stations start transmission at any time.
